iclaim. (01. 251-10) 7 The invention relates to valves of the. general projecting bearing necks t and I6 having axially type having a rock shaft, an'arm secured to said alined bearing openings I1, the axes of which rock shaft, and a valve secured to said armfor are parallel with the fiat face J3. A rock shaft cooperation with avalve seat, and while it is I8 is mounted in the bearing openings ll and 5 intended primarily for actuation by a gasometer projects beyond the neck it for connection with 5 to control the feeding of natural or manufacsuitable operating means, a portion of which is tured gas to a gas engine, it is usable also for shown at H). .The outer end of the neck I5 is various other purposes. l provided with a threaded cap 20 to be filled with.

The principal object of the invention is to prolubricant, and the outer end of the neck It is 10 videa simple, inexpensive and generally improved equipped with astufiing box 2!. This neck It 10 construction in which the seat and the pipe conis' also preferably provided with a grease cup or nections are carried by one block, and in which the like 22, for purposes of lubrication. the rock shaft, arm and valve are carried by a The rock shaft I8 extends across the recess 14 second block detachably secured to said one block. and an arm, 231' secured to the recess-spanning 15 Thus, upon release of the securing means, said portion ofsaid rock shaft, a set screw 24 being 15 second block and the parts carried thereby are preferably employed in securing said arm to said removable as a single unit from said one block rock shaft. This arm projects out of the recess without disturbing the pipe connections, both the M and beyond the side 53 of the block l2, and valve and the seat being readily accessible for its projecting end is provided with'a valve 25.

A second block I2 is provided, preferably in the accompanying drawing, it will be seen that the nature of a thick plate, said block l2 having ,I have made novel provision for carrying out the a flat side l3 and a recess l4 opening through objects of the invention, and while the details said flat side. The block l2 in the'presentdisr disclosed are preferred, variations may be made I claim:

A valve comprising an elongated block having its ends shaped for engagement with a Wrench, said block having a flat longitudinal side, a recess opening through said flat side, and alined threaded pipe-receiving openings in the block ends communicating with the ends of said recess, one end Wall of said recess being relatively distant from the corresponding end of the block and being provided with a valve seat around one of said openings; a second elongated and plate-like block having a fiat longitudinal side, a relatively small recess opening through said fiat side, and integral outwardly projecting alined tubular bearing necks at opposite sides of said recess, a cap threaded on the outer end of one of said necks,

a stuffing box threaded on the outer end of the other of said necks; a rock shaft permanently mounted in said tubular necks and projecting beyond said stufiing box, an arm having one end secured to said rock shaft within said recess of said second block, said arm projecting permanently from this recess beyond said flat side of said second block and having a valve on its projecting end; and means detachably securing said second block to the first mentioned block with the fiat sides of the two blocks in abutting relation; said arm extending into said recess of said first mentioned block and having its valve disposed in this recess in operative relation with said valve seat.
